Connection paths VS1, 2:
Here, those transmission system resources TR which are currently available are entered; the transmission system resources TR used by other connections V are respectively subtracted from the prescribed maximum transmission system resources TR. Similarly, at the end of a connection V, the transmission system resources TR1, 2 which become free on the connection paths VS1, 2 involved in the connection V which has been ended are subtracted again, i.e., are released again for other connections V.
